Hiccups in humans are caused by involuntary spasms of the diaphragm, a muscle that helps us breathe. These spasms can be triggered by various factors, including eating too quickly, drinking carbonated beverages, or even stress.
Hamsters don't have the same kind of diaphragm as humans, and their breathing patterns are different. So, while they might make sounds that resemble hiccups, they are not experiencing the same physiological phenomenon.
If you notice your hamster making unusual sounds, it's always best to consult a veterinarian to rule out any underlying health concerns.
